WebThe following formula tells us how to find P -1 given P: where d × d -1 = 1 (mod 26), and adj (P) is the adjugate matrix of P. The determinant of the matrix we are inverting is ac - bd (mod 26) = 15*19 - 12*2 = 261 = 1 (mod 26). We also need to find the inverse of the determinant (1), which luckily in this case is 1 because 1 is its own inverse.

WebAug 12, 2024 · The Hill cipher is vulnerable to known-plaintext attack. Once the attacker gets n plaintext/ciphertext pair it can break the cipher by solving a system of linear equations. Consider AES, it is not proved but considered secure against known-plaintext attack, see this question for details. And, also, key size itself doesn't represent the security.
